What is it about?
Adsorption processes govern the fate of molecules like glyphosate in different soil systems. The study is important, as glyphosate has been observed to play a significant role in diseases like cancer. Radiolabelling a molecule is a novel technique to determine the pathways of herbicides like glyphosate.

Why is it important?
The study clearly shows that the application of biochar is effective only in the Entisol soil systems. The clay mineral composition of different soils has been found to be the major factor influencing the trajectory of glyphosate molecule from the soil systems towards the water bodies.
Perspectives
The work in the publication is unique, as radiolabelling of herbicide molecules with C14 is a very expensive technique to study the fate of molecules, especially if the objectives are not clear. The study will help to understand the sorption behavior of glyphosate in different soil systems. From its initial application as a herbicide, glyphosate enters water bodies via different soil systems. High concentrations of glyphosate residues in ground or surface water can result in a plethora of diseases when consumed by human beings.
